not
act thus, (i.e., fluoresce); in which simple way real Diamonds can be
distinguished from false ones without any expert knowledge whatever.
For
effecting medico-surgical cures (as of superficial cancer, and allied
serious diseases of the skin,) the Radium is applied within a tube to
the afflicted anatomical part; when, after repeated use therof, it is
found that curative degeneration of the diseased tissues takes place;
and healing action becomes presently developed. For " moles," and "
port-wine " marks, a similar application of the Radium proves effective
to cure. The Radium is contained in a disc of wood covered with mica,
about a quarter of an inch in diameter. The patient holds it to the
affected spot for fifteen, or twenty minutes at each sitting.
As
the latest pronouncement on this subject of Radioactivity, M. Gustave
le Bon has shown convincingly that this is a general phenomenon, and
not solely the property of certain exceptional substances. He stoutly
affirms that all matter is of itself producing energy, chiefly
intra-atomic energy. He first discovered, and established the fact that
light falling upon bodies produces radiations which are capable of
passing through material substances. The original source of
Radioactivity is now believed to be the sun ; this Radioactivity
being known to consist largely of a stream of rapidly moving particles,
charged, either positively, or negatively, with electricity. Anyhow,
the main conclusions thus arrived at by leading scientists lend much
additional force to the arguments we are making bold to advance in
favour of positive influences for good, or harm, exercised on their
wearers, and users, by Precious Stones, and the Nobler Metals.
